supporting the spokes, a journal having double cone tapered toward opposite ends, two sets of taper rolls between. the double cone and'sleeves, and screw-collars fitted to the threaded spaces for adjusting the sleeves to the rolls. The double cone may bev locked upon the journalby clamping between and shoulders, in which case the wheel-hub is held from longitudinal motion by the opposed conical faces which bear upon therolls, or
the shelhmay be provided at oppositeiends withheads independent of the adjusting-cob lar; nd the bearing provided with a collar and nut adjusted to such heads. The collar and nut thus resist the end thrust, and the ing position between the rolls.
double cone insuch case may be titted movably to a feather upon the journal, so as to adjust itself longitudinally to a suitable worle Both constructions are shown in the annexed drawings, in which-- Figure 1 is a plan of the wheel-hub with the socket at the inner end of the journal by which it is jointed to the vehicle-axle for the purpose of steering. Fig. 2 is an end view of the hub and wheel-bearing with the hub in section at the end of the sleeve 9. Fig. 3 is a vertical longitudinal section of the wheelhearing. Fig. 4 is an end view, and Fig. 5 an edge view, of the adjusting-nutfor the journal. Fig. 6 is an end view, and Fig.- 7 an edge view, of the washer for the same. Fig. 8 is an end view, and Fig. 9 an edge view, of the head m. Fig. 10 shows the double cone detached from the journal. Fig. 11 shows one of the antifriction-rolls. Fig. 12 is "an end View, Fig. 13 a plan, and Fig. 14 an edge 5 view, of'one or" the roller-guides. Fig. 15 is a longitudinal section of the wheel bearing slightly modified. Fig. 3 shows the double cone splined upon the ournal to' adjust itself longitudinally, while Fig. 15 shows the cone clamped upon the adjusting thereto.
in Fig. 3, a designates the journal; I), the socket at right angles to the inner end of the journal for ointing it upon the axle. c is the shell of the wheel-hub, shown with flanges c to embrace the spokes or disk of the wheel. (I is a cap screwed into the inner end of the huh around the inner collar d of the journal. The outer end of the journal (1 is formed with a shoulder and with threaded extension d to receive the nut q. a designates a head screwed upon the outer end of the hub to close the same. fdesi ates the double cone tapered from the midd e toward its ends and fitted to the journal c by means ofa feather a, so that it can move longitudinally when required. g g designate the sleeves tapered cor respondingly to the double cone, at a slightly greater angle, to admit the antifriction-rolls which are tapered proportionately to the double cone and sleeves. The inner ends t of the rolls contact with one another and are of such conicalfshape and proportions, as shown in Figs. 3 and 11, that they roll upon one another with very little friction when pressed together by the operation of the hearing. The sleeves. the rolls, and double cone all roll upon one another without slippage. The enlargement of the rolls at their inner ends tends to make them slip endwise towardone another between the surfaces of the double sisted with very little -friction by the rolling contact of the opposed ends of the rolls. Feathers Z are fitted to keyways in the sleeves and shell to keep the sleeves from rotation. To adjust the sleeves to the outer surfaces of the rolls and to compensate for wear of the supporting-surfaces, collars m are screwed into the ends of the shell in contact with the shells, and such collars are bored to clear the journal (t, so that there. is no tendency for them to turn or lose their adjustment. llolos m (shown in Fig-'8) journal and the hub selfcone and sleeves. and such tendency is reserve to apply a spannerfor turning the col lars when required. To furnish longitudinal shoulders for the hub upon the journal, a collar d is provided at one end, and at the other a clamp-nut e is fitted to a threaded extension (1 of the journal, and heads n n are litted to shoulders within the ends of the shell to resist the thrust'upon these parts. The
clamp-nut is shown in Figs. 4 and 5 provided with a notched flange for turning it when required, and a lock-nut q is provided to am upon such clamp-nut and hold it from displacement when adjusted. To prevent the rotation of the head n from turning the clamp-nut, a washer 1 is titted between the clamp-nut and lock-nut to prevent the nuts from turning in a manner well known and provided with a tongue 8, fitted to a key-seat in the threaded end a and such washer is I- thus held from turning and prevents the clamp-nut from producing an tendency to turn the lock-nut. The doub e cone f is fitted to the feather (1/ upon the journal a, so as to adjust itself longitudinally between the rolls and sleeves, so as to produce an equal pressure upon both sets of rolls. To prc serve the integrity of the inner ends of the rolls which are designed to contact with and roll upon one another, the rolls are not mounted upon pivots, but are guided, as is common in roller-bearings, by means of a. plurality of guide-bars inserted between groups of the rolls and connected at their opposite ends by arches adapted to encircle or clear the journal. Such a guide-yoke is shown in Figs. 12 to 14, with the guide-bars connected by the semicircular arches 7i", and Fig. 2 shows two of suchguide-yokes applied to opposite sides of the journal to sustain four of the guidebars at equidistant points between the rolls. Such guide-bars are ex )anded or bent obtuscly at the middle of their length to clear the enlarged central portion of the double cone, and although the guide-bars are thus farther apart at the middle than at. the ends they are found in practice to guide the rolls satisfactorily and to prevent them from assuming any oblique position, which would cause them to grind and chafe violently against the shell and cone. Shoulders are shown in the shell 0 adjacent to the ends of the screw-threaded spaces which receive the collars m, and the heads n n are fitted to such shoulders, so 'as to receive'the end thrust of the journal independently of the screwcollars m,- whieh adjust the'sleevcs, and when any lateral bearing of the rolls upon the double cone arises the double cone slips automatically upon the leather (1 to restore the equilibrium of 'aressure in the two sctsof rolls.
In Fig. 15 the hub is shown without any heads and is not restrained from end movement upon the journal except by the fitting of the rolls between the (-one and sleeves. The double cone is shown in contact at its inner end witlrthe collar d upon the journal and at its outer end in contact with a bushing g, which extends through the collar m to contact with the nut g, and the cone is thus clamped rigidly upon the journal. The cone is secured upon t e journal by a feather'a. As the double cone cannot move upon the journal, the wheelhub automatically adjusts itself upon the double cone until an equal pressure upon both sets of rolls is secured, when the collar m is adjusted. In Fig. 15 rolls are shown formed of spiral coils, as is common in many roller-bearings.
The chief d'ifi'erence'between the constructions of Figs. 3 and 15 is that the end thrust in Fig. 3 is supported by the heads n n and the double cone is movable longitudinally upon the journal to secure an equal bearing upon the rolls 7L, while in Fig. 15 the double cone is clamped rigidly against the shoulder cl by the nut q and the end thrust is su tained directly by the collars m, which support and adjust the sleeves 9.
Having thus set forth the invention, what is claimed herein is 1. A wheel-hub having the shell 0 with cylindrical bore, and a keyway and screwthreaded space at each end of the bore, and flanges c for supporting the spokes, the journal a, having a double conef tapered toward opposite ends, the tapered sleeves g, g, fitted adj ustably to the bore and having feathers Z titted movably to the keyways, the screwcollars m fitted to the threaded spaces for adjusting the sleeves, and rolls fitted between such double cone and sleeves and tapered in the same ratio as the cone and sleeve.
